I-MPROVEMENT. IN THE COSTRUCTION OF BITCHES.

The ISchedule vreferred to in these Letters Patent and making o! the same To all whom it may concern: i

Be it known that I, Tonus K'. GRUBE, of Napoleon, in the county of Henry and State ot'Ohio, have 'inventeda new and valuable Improvement in the Construction of Ditches; andiI do hereby ldeclare that the following is a full, clear, and exact descrip- .tion ofthe constructionand operation of the same,

reference being had to the annexed drawing making a part of this specification, and to the letters and tigures of reference marked thereon. i

Figure l of the drawing is. aY longitudinal side view .ot' my invention in perspective.

Figure 2 is a 'sectional end view,l showing thel layer of leaves and earth above the frame. Fignres 3 and4 are details. My invention relates to means tbrpreventing ditches dug in loose or sandy soil from tilling up, -and consists inthe novel arrangement of a series of sticks therein, inclning upward,inward, and' forward from the base ofthe ditch, and secured together at the top, forming an angular frame-work, 'sloping like the eaves oF .a house; i l

The letterA of the drawing designates the series of sticks b, which forms the frame-work of my ditch.

vNVhen first laid, they are covered with a layer of leaves, moss, &c., in order to prevent the tiner partil 'cles of, earth from sifting through until the killing above the frame-work has become well settled.;

. My invention possesses the advantage of economy. It may be constrneted from refuse material'7 or sticksmay he iinished for the purpose. Such a. ditch will not till up, although existing in sandy soil.

A further veryiinportant advantage consists in the facility with whiehit may be adapted to any curve or'v bend, as in passing around a stulnp, 86e.

In commencing the ditch, I nsnally employ a prop.

or blo'ek, c, to support the tirst sticks.

What I claim as my invention, and desire to secure by Leiters Patent, is v The angular supporting frame-work A Composed of the sticks b, substantially as specified.

I n testimony that Iv claim the above, I have here- .unt-o subscribed my name in the 4presence oi' two wit- IIGSSBS.
